Answer:
a small deletion occurs in the nucleotide sequence at the aminoterminal of the gene in the signal sequence
Explanation:
A deletion in the sequence of nucleotide that code for the small signal sequence responsible will affect the release of insulin outside the cells because the signal sequence is responsible for carrying the insulin outside the cells. The cells of pancreas are producing the insulin normally but due to mutation in the signal sequence it can not release out of the cells and accumulate inside the cells.
Answer:
A because it is geneticly passed down
Answe<u>r:</u>
<u>light caused the elodea plants to photosynthesize, releasing O2 gas</u>
Explanation:
Oxygen is a by-product of photosynthesis. In presence of light, water molecules are split into hydrogen atoms and oxygen gas. The elodea plant is photosynthetic in nature. Later, the hydrogen atoms combine with carbon dioxide to form simple sugars like glucose in the dark stage.
Rivers, lakes and oceans are not sterile bodies of water. ... Water quality in a river changes because it is affected by many factors including weather, climate, rainfall, industrial and sewage discharges, and accidental spills. It is strongly impacted by runoff from rain events. Hope this helped!
